Identification Of Biomarkers Associated With Ascites Incidence In Broilers, Kaylee Rowland

Graduate Theses and Dissertations

Poultry is key in genetic research due to breeding feasibility, relatively short generation interval, and distinct phenotypes. It is estimated that 8% of broiler deaths annually can be attributed to ascites, an economically important disease that has been challenging the industry for the past 2 decades. Genetically selected ascites resistant (RES) and susceptible (SUS) chicken lines have been established and maintained by the University of Arkansas, Fayetteville. Intensive research efforts have been made to reveal physiological and biochemical characteristics for the incidence of ascites. Since the whole genome of the major ancestral chicken, the Red Jungle Fowl, has been sequenced, …

Barriers To Membership In The American Dental Hygienists’ Association In The State Of Georgia, Brandy Henderson

Electronic Theses and Dissertations

Professional associations must have a significant level of membership to be effective. Georgia membership is increasingly low; therefore, ADHA cannot represent dental hygienists’ interests. This study determined factors that caused dental hygienists to continue to forgo membership in the ADHA. Several theoretical views of professional membership were considered. The sample was acquired from an unbiased systematic sampling of 50% (3,270) of registered dental hygienists and a convenience sampling of ADHA nonmembers at 2 continuing education seminars in Georgia. Data collection procedures included an electronic cover letter, consent form, and survey via Survey Monkey or hard copies for seminars. Three hundred …

Evaluation Of Modafinil In Preclinical Behavioral Assays Of Abuse Liability, Amanda J. Quisenberry

Dissertations

Modafinil is an FDA-approved drug for the treatment of narcolepsy with efficacy in the treatment of chronic fatigue syndrome, obstructive sleep apnea, and shift-work sleep disorder. Modafinil’s wake-promoting and cognitiveenhancing effects are reportedly similar to those of traditional psychostimulants, but without the side effects typically associated with these substances. Modafinil has also been investigated as an agonist replacement therapy for psychostimulant dependence, although results of clinical trials are equivocal. Few studies have examined its behavioral effects in combination with psychostimulants and the neuropharmacological actions of modafinil are not well understood. The primary aim of this study was to assess modafinil’s …

The Lived Experiences Of Acute-Care Bedside Registered Nurses Caring For Patients And Their Families With Limited English Proficiency, Jami-Sue Coleman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Approximately 8.6% of the total U.S. population is considered limited English proficient (LEP), a term that has been used by official US federal policy and will be used throughout this study. In a landmark report, the Institute of Medicine found that minorities received lower-quality health care than Caucasians even when insurance status, income, and other factors were equivalent. These differences were tied to issues such as bias, stereotypes and communication barriers between patients and their caregivers. In the hospital setting, registered nurses provide the most direct contact with patients and their families. Effective communication between patients and health care professionals …

What Works In Suicide Bereavement: What Helps And What Hurts?, Quintin Hunt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Suicide is one of the most painful grief experiences that any family may experience. The suicide bereavement literature, though small, is replete with research that shows family and systemic impacts of suicide. The literature also includes constant calls for family- and systemic-based intervention as every part of society is impacted. Research in the field of marriage and family therapy, however, has ignored suicide and suicide bereavement almost entirely. The purpose of this qualitative study is to develop a more thorough understand of the grief that survivors of suicide experience and to systemically understand what helps and hurts the grieving process. …

Examining The Inner Experience Of Four Individuals With Bipolar Disorder Using Descriptive Experience Sampling, Johanah Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is a lifelong mood disorder with diagnostic criteria that provide a description of expected experiences of individuals diagnosed with BD (e.g., elevated mood, sadness, difficulty concentrating). Despite these criteria, the inner experience of these individuals is largely unknown. Understanding the inner experience of individuals diagnosed with BD may prove essential in understanding and treating BD. The present study examined the inner experience of four individuals diagnosed with BD using the Descriptive Experience Sampling (DES) method (Hurlburt 1990, 1993, 2011). Results revealed all our participants had clear and prevalent experiences of sensory awareness. They also had difficulties apprehending and …

Student Healthcare Providers' Illness Narratives: Impact On Family-Focused Care, Lindsey Ann Lawson

Loma Linda University Electronic Theses, Dissertations & Projects

In this study, we interviewed 30 students training for three areas of healthcare: medicine, nursing, and medical family therapy (MedFT). Through grounded theory analysis of these interviews, we looked to understand how these providers connected their own experiences with illness to their clinical work, particularly in including patients’ family members in care. The majority of participants, and especially those in medicine and nursing disciplines, described a tension between their desire to connect with patients and families and their developing definition of professionalism. For others, the impact of students’ personal experiences with illness seemed to provide a different definition of professionalism, …

The Effect Of Marriage On Stage At Diagnosis And Survival In Women With Cervical Cancer, Sanae El Ibrahimi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Marriage is associated with improved health outcomes for many conditions. Married persons enjoy financial stability, social and emotional support, and tend to have better control of health risk behaviors compared to the unmarried. The marriage scene is changing continuously. Americans are marrying less or delaying the engagement to an older age. They are divorcing more, they choose cohabitation as an alternative to marriage, or engage in premarital relationships. As a consequence, barely half of Americans were married in 2011 compared to close to three quarters of Americans were married in the sixties. With the increase of the unmarried population - …

The Impact Of Companion Animals On Social Capital And Community Violence: Setting Research, Policy And Program Agendas, Phil Arkow

The Journal of Sociology & Social Welfare

The term social capital has been used to describe the networks and other forces that build social cohesion, personal investment, reciprocity, civic engagement, and interpersonal trust among residents in a community. With the exception of three Australian reports describing positive associations between companion animal ownership and social capital, the literature has neglected to include the presence or absence of companion animal residents of communities as factors that could potentially affect social capital and serve as protective factors for community well-being. Companion animals are present in significantly large numbers in most communities, where they have considerable economic impact and provide emotional …

Effects Of Companion Animal Ownership Among Canadian Street-Involved Youth: A Qualitative Analysis, Michelle Lem, Jason B. Coe, Derek B. Haley, Elizabeth Stone, William O'Grady

The Journal of Sociology & Social Welfare

In Canada, approximately 150,000 youth are homeless on any given night, and many have companion animals. Through a series of semi-structured interviews, this qualitative study explored the issues and effects of companion animal ownership among street-involved youth from the perspective of the youth themselves. "Pet before self" was the substantive theme, with first level sub-themes of "physical" and "emotional" effects. Previously unidentified findings include benefits of having a companion animal, such as creating structure and routine and decreasing use of drugs. Loss of the companion animal was a negative effect. Youth consistently reported making choices to stay with their animal …

Attachment, Social Support, And Perceived Mental Health Of Adult Dog Walkers: What Does Age Have To Do With It?, F. Ellen Netting, Cindy C. Wilson, Jeffrey L. Goodie, Mark B. Stephens, Christopher G. Byers, Cara H. Olsen

The Journal of Sociology & Social Welfare

In part of a larger pilot study of dog walking as a physical activity intervention we assessed levels of attachment, social supports, and perceived mental health of 75 dog owners, identified through a tertiary- care veterinary hospital. Owners completed the Medical Outcomes Study (MOS) Social Support Survey, mental health component of the Short-Form-12 (SF-12) Health Survey, and the Lexington Attachment to Pets Scale (LAPS). Of particular interest was that younger owners had stronger attachments to their dogs (r = -.488;p <.001) and less social support (r = .269;p =.021). Our study suggests the importance of companion animals for social support, particularly for those without close friends/relatives. For younger owners, our study reveals vulnerabilities in support networks that may warrant referrals to human helping professionals. We suggest the use of Carstensen's Socioemotional Selectivity Theory as an interpretive framework to underscore the importance of including companion animals as part of the human social convoy, especially in terms of providing affectionate and interactional social support.

Faculty Publications

While studies have shown a relationship between family dynamics and contraceptive use and between contraceptive use and family well-being, no empirical study has been conducted to test whether a relationship exists between family influence on contraceptive use and family wellbeing. The objective of this study is to explore whether there is such a relationship between family influence on contraceptive use and family well-being.

New Mouthguard Design With Intermediate Nickel-Titanium And Foam Layer, Freddie Martinez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mouthguards help prevent orofacial injuries in many physical activities, commonly to the maxillary incisors. Mouthguards have many different properties which can be idealized. One property involves the amount of impact force the mouthguard can dissipate, commonly referred to as shock absorption. The aim of this study was to improve shock absorption capabilities beyond the protection that a mouthguard made of Ethylene Vinyl Acetate (EVA) can offer. A Nickel-Titanium (NiTi) and/or foam intermediate layer was placed between EVA. Seven configurations were fabricated at 3 different thicknesses. The configurations consisted of an intermediate layer composed of NiTi, foam, or NiTi/foam. The NiTi …

Relationships Between Landscape Factors And Crayfish Density And The Interacting Effects Of Grazing And Increased Sedimentation On Algal Biomass, Katheryn Haley Rose

Graduate Theses and Dissertations

In recent years in the United States there has been a rapid expansion in anthropogenic sources of sediment in streams including construction, agriculture, and drilling for natural gas. Potential effects land disturbance associated with activities from natural gas development on aquatic biota in surrounding streams have not yet been well documented. An increase in inorganic sediment in streams can be detrimental to organisms through a variety of mechanisms including alteration of dominant substrate type, higher turbidity resulting in lower visibility, and burial of food resources such as algae and detritus. Increasing sedimentation in stream environments through anthropogenic disturbance is a …

Balancing The Presentation Of Information And Options In Patient Decision Aids: An Updated Review, Purva Abhyankar, Robert J. Volk, Jennifer Blumenthal-Barby, Paulina Bravo, Angela Buchholz, Elissa Ozanne, Dale C. Vidal, Nananda Col, Peep Stalmeier

Dartmouth Scholarship

Standards for patient decision aids require that information and options be presented in a balanced manner; this requirement is based on the argument that balanced presentation is essential to foster informed decision making. If information is presented in an incomplete/non-neutral manner, it can stimulate cognitive biases that can unduly affect individuals’ knowledge, perceptions of risks and benefits, and, ultimately, preferences. However, there is little clarity about what constitutes balance, and how it can be determined and enhanced. We conducted a literature review to examine the theoretical and empirical evidence related to balancing the presentation of information and options.

Stress And Reproductive Hormones In Grizzly Bears Reflect Nutritional Benefits And Social Consequences Of A Salmon Foraging Niche, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits

Physiology Collection

Physiological indicators of social and nutritional stress can provide insight into the responses of species to changes in food availability. In coastal British Columbia, Canada, grizzly bears evolved with spawning salmon as an abundant but spatially and temporally constrained food source. Recent and dramatic declines in salmon might have negative consequences on bear health and ultimately fitness. To examine broadly the chronic endocrine effects of a salmon niche, we compared cortisol, progesterone, and testosterone levels in hair from salmon-eating bears from coastal BC (n = 75) with the levels in a reference population from interior BC lacking access to salmon …

Functional And Structural Changes Throughout The Auditory System Following Congenital And Early-Onset Deafness: Implications For Hearing Restoration, Blake E. Butler, Stephen G. Lombar

Brain and Mind Institute Researchers' Publications

The absence of auditory input, particularly during development, causes widespread changes in the structure and function of the auditory system, extending from peripheral structures into auditory cortex. In humans, the consequences of these changes are far-reaching and often include detriments to language acquisition, and associated psychosocial issues.Much of what is currently known about the nature of deafness-related changes to auditory structures comes from studies of congenitally deaf or early-deafened animal models. Fortunately, the mammalian auditory system shows a high degree of preservation among species, allowing for generalization from these models to the human auditory system. This review begins with a …
